css: Multiple class in same element.

Part of PraVeeN's adventure in General, Web Design

If you want to specify two style class’ in same element, put it like this:

class=“class1 class2″


(Another traditional way is put style tag also and put all the code in class there.)

Disable back button

Part of PraVeeN's adventure in General, Web Design

After the first test phase, it is always the problem for developers to handle browser ‘back button’ disaster. There are so many ways to handle this. But the way you select depends on the nature of your ‘probelm’.

Well, this method I liked much. 
<script language=“javascript”>
      history.go(1);
</script>


Put this in the of your page. This will allow the page to load only ‘forward’ and virtually disables the ‘backword’

Download any file from ASP.NET

Part of PraVeeN's adventure in General, DOTNET, C#, VB.NET, ASP.NET, PHP, Web Design

You know, some formats (txt, gif etc.) will be shown on the browser rather than downloading when we try. Below is the script which will help you to download any file. 


 
        Response.Clear();
        Response.AddHeader(“Content-disposition”, “attachment; filename=<filename>”);
        Response.WriteFile(“C:\</filename><filename>”);
        Response.End();
</filename>

The same logic is used in any server language.

Choosing the right programming language

Part of PraVeeN's adventure in General, DOTNET, C#, VB.NET, ASP.NET, PHP, OpenSource, Web Design, SQL

My students used to ask me “which programming language is the best?” and “which programming language I must learn?”. But the truth is – one cannot give an accurate answer for this. If somebody answers to this question simply - like C++ or Java, I will say he is a frog living inside a well. He may be giving this answer from his experience and knowledge, which is very less.

Contineous Javascript Marquee

Part of PraVeeN's adventure in Web Design

This script will let the text scroll contineously. This means, the second round scroll will start just after first round. This will overcome the in-between delay of HTML MARQUEE tag. However, this script is not free from limitations. But works on both IE & Firefox.


 
<html>
	<head>
		<script language=“javascript”>
		var text = “There is a long sentence With some more text However as soon as this message plays There’s a really long break Before the text starts Over.”; // User Text
		var i = 0;
		var n = 50;	// Number of Charaters to display
		var speed = 50; // Scroll speed in milliseconds
		text = text + text.substring(0,n)
		function marqueeText() {
			document.getElementById(“divText”).innerHTML = text.substring(i,i+n);
			i++;
			if (i > text.length - n ) i = 0;
			setTimeout(‘marqueeText()’, speed);
		}
		</script>
	</head>
	<body>
		<div id=“divText” style=“border:solid 1px gray;background-color:#CCCCCC “ align=“center”></div>
	</body>
</html>
 
<script language=“javascript”>
	marqueeText();
</script>
